WALTER L. MONTGOMERY, OF CHICAGO, ILLINOIS.

AUTOMA'I'IC DEVICE FOR RECEIVING AND DISCHARGING CARTONS.

T 0 all whom it may concern:

Be it known that I, WALTER L. MONTGOM- FRY, citizen of the UnitedStates, residing at Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements in AutomaticDevices for Receiving and Discharging Cartons; and I do hereby declarethe following to be a full, clear, and. exact description of the1nvention,'- such as will enable others skilled in the art to which itappertains to make and use the. sa-Ine.

This invention relates to improvements in a receiving and dischargingmechanism, associated with an automatic weighing and filling machine,and one of. the objects of the invention. is to provide a receiving anddischarging mechanism automatically thrown into operation by the weightof the filled container. V

A; further object of the invention is to assist the discharge mechanismin removing the filled container from the platform of the dischargemechanism, such assisting means being in operation only whenthecontainer is full.

With these and other-objects in view the invention comprises certainnovel constructions, combinations and arrangement of parts as will behereinafter more fully described and claimed.

Figure 1 is a side elevation .of the mecha-' responding parts throughoutthe severalviews. a

The mechanism disclosed in this invention is designed to beplacedbetween thehottom sealing machine and the top sealing machine and placeddirectly under the weighing and fillin machine.

Generally t e invention resides in a vertically r'evoluble platformsuitably balanced, the said platform being depressed by the weight of afilled container, which automatically throws it in gear for rotating theplatform which discharges the package to a moving conveyer belt.

Referring more specifically the draw- Specification of Letters Patent.Application filed September 18, 1912. Serial No. 721,097.

charging conveyer belt being located at' 1Eight angles with thereceiving conveyer elt.

Rigidly secured to the frame 1 is a ver- I tical tubular member 2carrying at the upper end thereof a collar 3 which supports .a normallyrotating clutch member 4, which is provided with a groove 5 forreceiving a belt for driving the same. The upper part of the frame 1 isprovided with a cross brace 6 through which passes a shaft 7 carrying atthe lower end a clutch member 8 adapted to engage the inner surface ofthe clutch member 4 when the shaft 7 descends. The lower end of theshaft member is reduced and passes through the normally rotating clutchmember 4 into a tubular member 2.

Pivoted in the frame 1 as at 9 is a lever 10, one end 11 of which isbifurcated and engages the shaft 7 between a pair of suitable collars,it being understood, however, that any other suitable means ofconnecting the lever 10 with the shaft 7 may be used. The other end ofshaft 10..is adapted toreceive an adjustableweight 12, this weight beingsuch as to balance the weight of the shaft 7, the clutch member 8, and acircular platform 13 rigidly secured to the shaft 7. By means of thisweight 12, the platform 13 is normally held in position as shown in Fig.1.

Keyed to the shaft 7 is a suitable wheel 14 engaging, an elongatedpinion 15 in the frame 1, this pinion 15 being designed in turn toengage a gear wheel 16, which is secured by means of a shaft. to 'aroller 17. The surface of this roller 17 may be covered with rubber orny other substances which will frictionally engage the sides of thecontainers to be delivered. Arranged in front platform 13 than theroller 17 By this.

mechanism it will be seen that the roller 17 will be turned through themedium of the gears whenever the shaft 17 is caused to rotate.

To one side of the platform 13 is formed guides being to form arestricted pathway through which the empty containers may pass to theplatform 13.

Arranged beside a discharging conveyer belt 25 and extended backwardlytherefrom is a guide bar 22, which with the guide bar 23 projecting fromone of the guides forms a pathway through which the filled containersmay pass from the rotating circular platform 13 to the conveyor beltleading to the top sealing machine. The edges of the rotatingplatformare beveled, as shown, the purpose of the bevel being to allowthe top of the conveyer belt 25 to be as near as possible to the top ofthe platform 13 when the latter is in its lowest position.

In the operation of this mechanism, the empty containers are deliveredto the stationary platform 19 when the rotary circular platform 13 is inits elevated position and the clutch member 8 is disengaged from theclutch member- 4 through the medium of adjustable weight 12. :As theempty container arrives upon the platform 13, the same is filled from asuitable weighing and filling machine indicated diagrammatically at 24.It is designed to have the shaft 7 so balanced with the adjustableweight 12 that when the container has been filled, the weight of thesame will be sufficient to overcome the weight of the adjustable member12 as and the shaft 7 will descend, the clutch 8 engaging with theclutch member 4 which is normally rotating. The rotation of the clutch 8by means of the clutch 4 will rotate the platform 13 in the directionindicated by the arrow, Fig. 3. The filled container, which has one sidethereof in engagement with the roller 18 will slide along said. rollerand be thrown against the elongated roller 17. From the mechanismalready described, it will be apparent that the roller 17 is alsorotating, such rotating being simultaneous with the rotation of theshaft 7. It will be noted that by means of the intermediate gear 15, theshaft 17 is made to rotate in the same direction as the rotatableplatform 13, so that as the filled container moves in the directionindicated by the arrow, the side which engages the shaft member 17 willbe pushed along in the same direction as that shown by the arrow on theplatform 13. The platform 13 and the roller 17 will rotate so long asthe weight of the filled container is thrown upon the platform 13, andthe belt 25 will engage theadvancing end of the filled container beforesaid carton has been completely removed from the latform 13. It will benoted that the gui e rod 22 leads out from the roller 17, so that thatedge of the filled container which engages the said roller will beguided along the guide rod 22 and be picked up by the conveyer belt 25.It may be noted that the two rollers 17 and 18 are mounted upon anextension of the ide rod 22,this extension being secured to t e frame 1in any suitable manner.

From this description, it will be apparent that an auxiliary mechanismis thrown into operation for delivering the container as soon as it iscomplete, and also an auxiliary friction roller is caused to operate atthe same time, the direction of rotation of the roller being such as toassist the discharging of the filled container.

What is claimed is:

1. In a machine for receiving and dis- 0 charging containers, a normallyrotating member, a balanced rotatable platform mounted to movevertically, and means associated with the platform and moving therewithfor engaging the rotating member as the platform descends, and aconveying device having its upper surface in the same plane with theplatform when the latter is rotated.
